We just replaced the parkingirl's bulbs on our 07 xls and now neither are working.

Any ideas?

We are also having electrical issues inside with the door switch for the dome lights. No dome lights work at all, even when manually switched on.

 

So is it safe to assume that they were not working before you changed them out. If they were not, I would start checking fuses to see if that's the problem. If it's a fues, then you have to wonder why it blew in the first place. get a volt meter to see if you have voltage for the dome lights. If not start at the fuse box.
